It sounds like the recipe for a viral Instagram post: a swimsuit, a shipwreck and sea turtles. But a team of researchers studying the interactions between divers and marine life are learning that social media may be more useful than inflating your online ego. The scientists are using Instagram posts to survey sea turtle populations, while also learning about the way that divers behave around them. In a study published recently in the journal Animal Conservation, the team suggests that Instagram could be a useful tool for other scientists hoping to learn how sea turtles interact with shipwrecks.
